Stainless steel coil plates should be understood. There are many types of cold rolled plates, which can be classified according to shape and size or according to processing technology. For example, the difference between C-shaped roof purlins and Z-shaped roof purlins depends mainly on the focus. Generally, C-type products are 90 degrees, while Z-type products cannot achieve such a focus, only about 60 to 75 degrees. Therefore, steel purlins are used differently with different inclinations. In terms of function, the structural mechanical effects of the strong axis and the weak axis of the cold-drawn C-type roof purlin are quite different, so their structural mechanical effects must also be different. Therefore, during the processing process, there are strict regulations on the standards and material selection of cold-rolled plates. Steel frame structures with different cross-sections have different bearing capacities to support and adapt to different working conditions. Because of this purposeful application advantage, there are different products and great functional advantages in application. At the same time, we must talk about the strength index of cold-rolled steel sheets, which is the ability of the material to withstand the pressure of hard objects on the surface. According to different test methods and application...
Word of mouth is the sense of satisfaction and honor gained by customers in the process, which forms a gradually increasing word-of-mouth publicity effect to the outside world. Customer satisfaction is not only satisfied with the results, but also more picky about the process. Only when customers’ needs are met will they voluntarily spread word of mouth. The above is a brief introduction about “steel strips for stainless steel pipes”. Due to the gaps in the equipment and component structures or the presence of metal or non-metallic deposits on the surface of stainless steel pipes, gaps are formed between the deposits and the surface of the stainless steel pipes, which act as corrosive media. Under this condition, point-like and spherical damage will occur preferentially at the crevices, which is crevice corrosion. In water media containing Cl- and other water media, the partial passivation film is caused by acidification and lack of oxygen in the media solution in the gap. The fundamental way to eliminate gaps is to avoid gaps in structural design. The gaps between the heat exchange equipment tubes and the tube sheets should be cleaned regularly and exposed to seawater and other environments to prevent dirt from accumulating...
Stainless steel pipes have low strength and hardness and are not suitable for equipment or components that bear heavier loads and have higher requirements for hardness and wear resistance. Especially under the condition that multiple factors such as corrosion, wear and external load exist at the same time, the result of the interaction will significantly accelerate the material process and shorten the service life of stainless steel pipes. The content described in “The quality of stainless steel pipes can be inspected from many aspects” was carefully prepared by our editor for everyone. Do you still remember what was said in the previous article? These may be somewhat incomplete, and we will explain them one by one in future articles. I hope that through the introduction of this article, you can have a certain understanding of the quality of stainless steel pipes, which can be inspected from many aspects. The quality of stainless steel pipes can be examined from many aspects, so when choosing a good stainless steel pipe, you must pay attention to how to distinguish the quality of stainless steel pipes. The steel strips of refining furnace stainless steel pipes are made from ores and other materials with refined...
1. Mechanical polishing method: The abrasive material and the pipe surface are ground through mechanical force to achieve the purpose of removing surface defects. Commonly used grinding tools include grinding wheels, abrasive belts, grinding cloths, etc. The advantages of mechanical polishing are high processing efficiency, low cost, and suitable for mass production. The disadvantage is that the surface is rough and prone to scratches and residues. 2. Chemical polishing method: Surface defects are repaired through chemical reactions to improve surface finish. Commonly used chemical polishing agents include nitric acid, hydrofluoric acid, phosphoric acid, etc. The advantage of the chemical polishing method is that it has good surface quality and can remove minor defects and burrs. However, the disadvantage is that it is difficult to operate, requires strict control of process parameters, and the waste liquid and waste gas generated pollute the environment to a certain extent. 3. Electrochemical polishing: Its advantages are long-lasting mirror gloss, stable process, less pollution, low cost, and good corrosion resistance. Its disadvantages are high pollution prevention, large one-time investment in processing equipment, complex parts requiring tooling and auxiliary electrodes, and mass production also requires cooling facilities. It is suitable for mass production and is mainly...
